IPC: C01G47/00
Filed: 1929-02-27
Abstract: 317,035. Siemens & Halske Akt.-Ge,s. Aug. 9, 1928, [Convention date]. Rhenium compounds. - Rhenium is extracted from molybdenum ores or compounds by dissolving the molybdenum as trioxide for instance in nitric acid and precipitating molybdenum for instance as phosphomolybdata with ammonium nitrate and phosphoric acid or a phosphate, leaving the rhenium and some molybdenum in solution. From the latter rhenium and molybdenum are precipitated together by hydrogen sulphide and the precipitate re-dissolved in nitric acid, the steps of precipitation of phosphomolybdate, treatment with hydrogen sulphide, and resolution in nitric acid being nepeated until the solution contains say ¢-2 per cent of rhenium with respect to the molybdenum still present. Rhenium is then recovered as by fractional sublimation, the sulphide concentrate being reduced by hydrogen and then gently heated in a current of oxygen, reduction, fractional volatilization, and re-oxidation of the sublimates being repeated to separate the rhenium. It is stated that rhenium may be similarly recovered bv fractional sublimation of a mixture of chlorides.

Filed: 1947-03-12
Abstract: 626,387. Spray producers. HESSION, J. W. March 12, 1947, Nos. 6888, [Convention date, March 15, 1946], 6889, 6890 and 6891, [Convention dates, Feb. 26, 1947]. [Class 69 (iii)] A method of converting liquids into aerosols consists in feeding a liquid through a hollow shaft 10 into a hub 6 having dispensing channels 47, 48 in communication with a space between two discs 1, 2, which are in contact at their peripheries 5<SP>1</SP>. In operation the shaft 10 and discs 1, 2, are rotated at high speed, driving the air out by centrifugal force and creating a low pressure sufficient to throw the liquid from a container (not shown) up the interior 11 of the shaft 10 into the space between the discs, from which space increasing centrifugal force drives the liquid between the discs in a thin film of a few microns thickness, and finally from the peripheral edges of the discs in a finely-divided aerosol. The aerosol leaving the periphery of the discs is cradled by an air current from a fan (not shown) which issuing from the annular space v as indicated by the arrows w directs the aerosol at right-angles to its original direction and projects it for a considerable distance before it is caught by air currents and allowed to drift. In an alternative arrangement multiple layers of discs separated at the centre and clamped together at their peripheries are employed, the number of discs being governed by the volume of aerosol required. The quantity of liquid dispensed to the discs is regulated by an adjustable screw 49. Variation of the particle size is effected by adjustment of the speed of rotation, or size of discs employed, and also by regulating the volume of liquid feed, an increase in liquid feed forcing the discs apart at the peripheral area and resulting in the formation of larger sized particles in the aerosol. Various mechanical arrangements of discs and driving motors are described in the examples given in the Specification.
Patent GB-180447-A (GB)
Title: Processes for resolving emulsions
IPC: B01D17/04
Filed: 1921-03-03
Abstract: In order to resolve emulsions, reagents are added which are colloidally soluble in the continuous phase of the emulsion but which, when brought in contact with the disperse phase, act as emulsifying-colloids tending to reverse the form of the emulsion. As examples, a mixture of 25 per cent of sodium soap, 10 per cent of water and 65 per cent of oleic acid is stated to be colloidally soluble in oil, but to act as a reagent for resolving an emulsion of water in oil in virtue of the contained soap. Conversely 4 per cent of calcium oleate dissolved in a mixture of equal parts of alcohol and glycerine, with the addition of 1 per cent of gelatine is stated to be colloidally soluble in water, while the calcium oleate acts as a reagent for resolving an emulsion of oil in water.  The reagent may contain a substance adapted to dissolve both the continuous phase and the emulsifying-colloid.  For example resin soap containing free resin may be added to an emulsion of water in oil, the free resin dissolving both the resin soap and the oil.  Fresh or salt water in crude petroleum and cotton seed oil in soap stock are examples of emulsions stated to be resoluble by this method.  The constituents of the resolved emulsions may be separated by settling or by centrifugal action.
